# Objective - I'm compiling (parts of) bevy for an embedded platform with no 64bit atomic and ctrlc handler support. Some compilation errors came up. This PR contains the fixes for those. - Fix depth_bias casting in PBR material (Fixes #14169) - Negative depth_bias values were casted to 0 before this PR - f32::INFINITY depth_bias value was casted to -1 before this PR ## Solutions - Restrict 64bit atomic reflection to supported platforms - Restrict ctrlc handler to supported platforms (linux, windows or macos instead of "not wasm") - The depth bias value (f32) is first casted to i32 then u64 in order to preserve negative values ## Testing - This version compiles on a platform with no 64bit atomic support, and no ctrlc support - CtrlC handler still works on Linux and Windows (I can't test on Macos) - depth_bias: ```rust println!("{}",f32::INFINITY as u64 as i32); // Prints: -1 (old implementation) println!("{}",f32::INFINITY as i32 as u64 as i32); // Prints: 2147483647 (expected, new implementation) ``` Also ran a modified version of 3d_scene example with the following results: RED cube depth_bias: -1000.0 BLUE cube depth_bias: 0.0  RED cube depth_bias: -INF BLUE cube depth_bias: 0.0  RED cube depth_bias: INF (case reported in #14169) BLUE cube depth_bias: 0.0 (Im not completely sure whats going on with the shadows here, it seems like depth_bias has some affect to those aswell, if this is unintentional this issue was not introduced by this PR)
